Hi,
need some help with freeing interupts. In my code in init I call :ret = request_irq( interruptNumResp, FRTransHnd_run, IRQF_PERCPU,"response", pHandler);		in exit function I call:free_irq(interruptNumResp, NULL);
but after rmmod that I got:
Trying to free already-free IRQ 59 message and than I can't insert mymodule again.
Is there something what I'm doing wrong?
Thank's in advance
